A structural support apparatus for positioning in a downhole tubular string includes a support structure base and a liner ring having a first contact load surface in contact with a contact load surface of the base. A fastening mechanism is positioned between the base and the liner ring, where the fastening mechanism is configured to prevent movement of the liner ring relative to the base. A method for fastening a liner ring to a support structure apparatus in a downhole tubular string includes positioning a first contact load surface of the liner ring along a contact load surface of a support structure base. A second contact load surface of the liner ring is positioned along a frangible disk. A fastening mechanism is positioned between the base and the liner ring, where the fastening mechanism is configured to prevent movement of the liner ring relative to the base.

A toe valve () comprising; a housing () having an interior and exterior; a sliding sleeve (); a counter mechanism () comprising a cylinder, a ratchet piston () with first and second ends, and a ratchet shaft () connected to the second end; a trigger assembly () comprising a trigger housing, and a release piston (), wherein the trigger assembly () is arranged between the counter mechanism () and the sliding sleeve (), and wherein the release piston () is configured to activate the sliding sleeve (), and the ratchet shaft () is configured to activate the release piston (), wherein the toe valve () further comprises; a closed chamber () enclosing the ratchet shaft () and defined at least partly by the cylinder comprising a chamber fluid with a chamber pressure (P); an inlet pressure port () configured to be in communication with a wellbore fluid with a wellbore pressure (P), and wherein the first end of the ratchet piston () is in fluid communication with the inlet pressure port (), wherein the ratchet piston () is configured to move towards the trigger assembly () to a new position and compress the chamber fluid when the wellbore pressure (P) is larger than the chamber pressure (P); a retaining mechanism () configured to retain the ratchet shaft () in the new position; and a valve mechanism interconnecting the first and second ends of the ratchet piston () and configured for equalizing the pressure across the ratchet piston ().

Self calibrating toe valve

Stimulation sleeve () for well intervention in a subterranean wellbore, comprising: a housing () having a through channel () with a first end () and a second end (), and one or more flow ports (), and a sliding sleeve () disposed axially movable within the housing () to open or close said flow ports (). Said sliding sleeve () is equipped with at least a first obturator seat () for receipt of a obturator () to partially or fully close fluid communication in the through channel () of the housing (), and a time delay mechanism () to allow the sliding sleeve () to axially travel in the housing () at a predetermined speed to open or close said flow ports (). The invention also discloses a method for well completion in a subterranean wellbore using a sliding sleeve ().
